This and the other water heater descriptions may be the salient point - the
electrode is totally emersed in the electrolyte and is
separated from the tank by the electrolyte except at the one point - the top of
the tank. Therefore the current flows from the
electrode thru the electrolyte to the tank then back to the electrode at the
single connection. A really spiffy battery.
By simply laying the electrode in the bottom of the air tank the electrolyte
separation of the electrode and the tank would seem to
be severly compromised - you would simply have a damp piece of electrode lying
in the bottom of the tank. Yes, we could then begin
thinking about it as as millions of very small electrode - electrolyte - tank
connection - batteries ... and are they in series or
in parallel and ... My head is starting to hurt trying to work out where the
current would flow.
